Aged mango high-pile grafting method

Abstract

The invention provides a high-pile variety changing method for aged mango trees, which is characterized in that: 1. in an earlier stage of grafting, an annular ditch which is 30 centimeters wide and 40 centimeters deep is dug on the periphery which is 1 to 1.5 meters away from the root of a mango tree, so as to cut off a root system, reduce the transport of moisture and nutrients and achieve the balance between moisture and nutrients after grafting; 2. a position on the mango tree, which is 0.8 to 1 meter away from the ground, is integrally cut once and for all and is grafted by a cut grafting method; 3. a scion and a pile body are sprayed with carbendazim 2 to 5 days after grafting, and a tree body is brushed with quicklime plus 4-6 mass percent table salt liquid after 7 to 9 days of grafting; and 4. when a new grafted survived treetop grows to 15 to 20 centimeters, the new tree top is pinched in time so as to promote branching and form a tree crown rapidly. The method ensures that the survival rate of grafting and changing the variety of the aged mango trees reaches more than 93 percent; a new tree crown in the second year after grafting can reach more than 2 meters; and single plant can bear more than 8 kilograms of fruits on the average. The method has the advantages of shortening the reformation period of aged mango orchards and improving the economic benefit of the orchards.

Description

technical field [0001] The invention relates to a method for replanting mango trees with high piles, in particular to a method for replanting old mango trees with high piles. Background technique [0002] Mango is a tree species with a long lifespan, but it has been planted for many years, and there are problems such as species degradation and low yield. Using high-grafting methods, replacing it with high-quality new varieties, and improving the variety of mango orchards is the adjustment and optimization of mango varieties. structure, a fast and effective way to improve the economic benefits of mango. At present, for the transformation of old mango trees, one adopts the method of sawing off the main side branches, taking out new shoots at the saw kerf and grafting on the new shoots after they are mature, but there is a problem of long transformation period; The method of grafting, but there is the problem that the canopy cannot be dwarfed.
